How the ctr calculator works
Click-through rate (CTR) is the percentage of people who clicked after seeing your ad, link or email. The formula is clicks ÷ impressions × 100. It measures how compelling your creative and targeting are at turning views into clicks, and it directly affects your costs: higher CTR usually means cheaper clicks and better ad placement. This calculator computes it instantly in your browser.
A "good" CTR depends entirely on context, a search ad, a display banner, an email and an organic search result all have very different typical rates. Display banners often sit well under 1%, while a well-matched search ad or email can be several percent. Compare like with like.
Frequently asked questions
What is click-through rate (CTR)?
CTR is the share of viewers who clicked, calculated as clicks ÷ impressions × 100. It shows how effective your headline, creative and targeting are at earning a click from the people who saw your content.
What is a good CTR?
It depends heavily on the channel. Display banner ads often run below 1%, search ads commonly land a few percent, and a well-targeted email can be higher still. Benchmark against the same channel and your own past results.
How is CTR calculated?
CTR = clicks ÷ impressions × 100. For example, 450 clicks from 30,000 impressions is 450 ÷ 30,000 × 100 = 1.5%.
Why does CTR matter?
A higher CTR usually lowers your cost per click and improves ad rank, because platforms favour ads people engage with. It also signals that your message matches your audience, which tends to improve everything downstream.
